Thisinvention relates to a tension device for winding machines, thegeneral object of the invention being to provide means for controllingthetension of the thread or yarn as it is drawn off of a yarn carrier onto a receiver so as to wind the yarn evenly upon the spool and to freeit of kinks and to make the device so that it can be adjusted fordifferent grades of yarn.

Another object of the invention is to provide a plurality ofwedge-shaped weights, with holding means for the same so that a weightof any desired size may be used with the device according to the kind ofyarn being spooled.

This invention also consists in certain other features of constructionand in the combina tion and arrangement of the several parts, to

be hereiaft r fully describe'd,"illustrated in the accomp nying drawingsand specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is an elevation of the device.

Figure 2 is a front view thereof.

Figure 3, is a plan view.

Figure 4 is a section on line. 4-4.- of Figure 3.

Figure 5 is a section on line 5-5 of Figure 4.

Figures 6, 7 and 8 are perspective views of the weights.

, Figure :9 is a section on line 9- 9 of Figure 1.

In these views, the numeral 1 indicates an upright which is formed witha forked lower end to engage the transverse bar 2 of the machine onwhich the device is used, a bolt 3 acting to clamp the upright to thebar. This upright is formed with a slot 4 having notches 5 in one of itsvertical walls and with a ver- 4 tical row of holes 6.

The spindle 7 for the bobbin 8 is carried by a substantially L-shapedbracket 9, the long arm of which is formed with a slotted angularextension 10, through the slot of which abolt 11 passes, this bolt beingadapted to engage passes after it leaves the guide 15. 1 A similar-1928. Serial No. 294,166.

.any one of the notches 5 whereby the bracket can be adjusted verticallyon the upright. A teat 12 is carried by the extension 10 and is adaptedto engagev any one of the holes 6 in the upright. A looped guide carrier13 is adjustably connected with theupper part of the upright by the bolt14 which passes through the looped part of the carrier and a guide 15,preferably formed of porcelain, has a threaded part passing through theeye of the long arm of the carrier, with a nut 16 on the bolt forclamping the guide to the carrier.

A forked plate 17 is fastened to the inclined upper end 18 of theupright by the bolt 19 and the wing nut 20 so that this plate can beremoved when desired. A' depending plate 21 is fastened to one prong oftheforked plate 17 by having its upper end bent to engage the prong anda bolt 22 passes through a Washer plate 23, a slot in the bent upper endof the plate 21 and through the prong. The lower end of the plate 21 isprovided with a slot 24 through which the thread or yarn 1y shaped plate25 'is adjustably connected with the other prong of the plate 17 by thebolt 26 which passes through a slot 27 in the prong and through the bentend of the plate 25. s will be seen, the plate 21 is adjustable towardand away from the plate 25, while the plate 25 is adjustable at rightangles to the plate 21. The plate 25 is also much shorter than the plate21. The plates 21 and 25 are convergently arranged, with a space betweentheir lower portions and as will be seen from Figure 4, the two platesform a V-shaped recess. A channel member 28 iscarried by the plate-25,the flanges of the member tapering downwardly with the tapered part ofthe member extending into the V-shaped recess as shown.

Any one of a number of wedge-shaped Weights, such as shown at 29, 29 and29" in Figures 6, 7 and 8, is adapted to be placed in the channel memberwith its operative face resting against the plate 21 and thus engagingthe thread and acting to-place the same under tension. After leaving theweight, the 100 thread passes over a stationary roll 30 held in thelimbs of a U-shaped member 31 which is adjustably connected with theplate 17 by the bolts 32 passing through slots 33 formed in the bight ofthe member 31. A long bolt '34 passes through the roll 30 and throughtightening the nut, the arm will be held in ad justed position.

From the foregoing it will be seen that the 2. A tension device for awinding machine comprising a support, a pair of convergent memberscarried by the support and forming a V-shaped recess, the lower end ofwhich is open and one of the members having a notch in its lower endwhereby a thread can passthrough the notch and through the recess and awedge-shaped weight in the recess and pressing the thread against one ofthe convergent members;

In testimony whereof DAVID PALIN.

bracket 9 can be adjusted vertically to place the bobbin any desireddistance from the guide 15 and that the weight holding member 28, aswell as the roll 30, can also be adjusted to suit the conditions underwhich the device is working. The thread can be guided by one handthrough the Me 15, the slot 24; and through the space 'etween themembers 21 and 28, the weight carried by the member 28 holding thethread in position. Then the thread is carried over the roll 30 underthe arm 36 to the spool.

By adjusting the arm 36 in relation to the roll 30, the tension'exertedon the thread or yarn can be controlled and if this tension is notsuficient, a heavier weight can be placed in the member 28 so that byusing the proper size weight and adjusting the'arm 36, the

proper tension can be placed on the thread or yarn to remove kinks andto form a hard spool with the thread evenly wound thereon.

As will be seen, this device is extremely simple and can be easilyassembled and the parts can be easily and quickly adjusted according tothe kind of yarn being used and any part can be replaced when worn orbroken. By removing the forlred plate 17, the

parts carried thereby can be used on other kinds of winding machines.

lt'is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction andin the combina tion and arrangement of the several parts, provided thatsuch changes fall within the scope of the appended claims,

W hat I claim is:

l. A tension device for a winding machine comprising an upright, meansfor attaching it to a part of the machine, a plate attached to the upperend of the upright, a pair of depending convergent members carried bythe plate, one of which has a slot therein, holding I means on the othermember, and a wedge-- shaped weight removably held by the holdmg meansand engaging one face of the slotted convergent member,
